EDDG V. BATES, 0F LOWELL, MASSACHUSETTS.

Application filed October 9, 1918.

T 0 all whom it may concern:

Be it known that I, Enno V. Barns, a citizen of the United. States, residing at Lowell, in the county of Middlescx and State of Massachusetts, have invented certain new and useful improvements in Garnett lVorker- Breasts for ool-Cards, of which the following is a specification.

This invention relates to what are known as breasts for woolen cards. It is of a type similar to those shown in patents to E. V. Bates on breast for carding machines, Nos. 1,103,6429, July 14, 191i, and masses, De-

cember 7, 1915, wherein a breast cylinder and other rolls cooperating therewith are located at the feed end of a card with little, if any, change in the arrangement of the main cylinder, workers, strippers, lickerin, tumbler, etc.

My device is particularly useful on the first breaker card, as the stock fed to such first breaker is generally made up of matted locks and, especially with low grade stock, contains pieces of cloth, which must be torn up, together with buttons, seeds and other impurities which should be removed. My device may, however, be used as described herein or, with the slight modifications familiar to every carder, on the intermediate or finisher cards.

Especially when used on the first breaker, I prefer that all my rolls shall be covered with flat wire or garnett wire instead of with card clothing, as cylinders covered with such wire are stronger and he teeth thereof are not so readily bent or injured.

The particular feature of this invention the use of a worker covered with garnett wire in carding contact with the main cylinder and also preferably with the breast cylinder. I believe thatl am the first to use such a garnett wire worker in carding contact with a main cylinder covered with card clothing, and particularly such a worker also arranged to card with the breast cylinder and toreturn'any lumps, looks or other pieces of material from the main cylinder to 1 the breast cyl nder before they have passed i on to the other workers and strippers of the card covered with the ordinary card clothing.

' As the stock is placed lightly on the main cylinder by the tumbler and any looks or bunches stand upon the teeth thereof, such locks and hunches are easily removed by Specification of Letters Patent.

Serial No. 257,467.

such worker especially if, as I prefer, its

teeth have considerable pitch or rake.

My device is substantially a re-working breast with fiat wire tooth rolls including especially a worker which'not only cards with the main cylinder but serves as a guard to prevent rough stock from beingcar-ried along by the main cylinder to the injury of the card clothing thereon and to that on the workers and strippers.

In my preferred construction, I use a lickerin, preferably of the bur roll type covered with flat wire teeth, which takes stock from the feed rolls and carries it up ward, its teeth being arranged point topoint with those on the breast cylinderwhereby something in the nature f carding occurs to the extent that the parts of such locks, pieces or" cloth, etc., as stick up on the teeth of the bur roll lickerin are pulled away and picked off by the breast cylinder, leaving small parts and finer pieces in the teeth of the bur roll. By running my lickerin forward, I can watch the stock as it runs thereon. My tumbler is preferably so arranged as to clear the teeth ofthe breast cylinder and of the bur roll, and to transfer the stock fromboth to the main'cyb inder.

My breast is easllyfattached to an old card, and Every simple, easy to clean and does not interfere with the operation or cleaning of other parts nor. withthe view of them.

By card clothing, I mean clothing with:

an elastic or yielding foundation and round wire teeth.

Under flat wire teeth, I include convert wire toothed card clothing, garnett wire with saw teeth, and bur cylinder wire with flatmetallic tooth wire;

vSuch metallic tooth wire will not bend By forward runnmg, applied to rolls and cylinders, I refer to the direction in which topped teeth, both known to thetrade as the top moves from the feed end of the card toward the delivery end, or from leftto right in the drawings, and by backward runnmg Irefer'to theopposlte direction. By

forward'pitc'hing, applied to teeth,l reier to the rake, from base to point when at the top of a roll, being toward the delivery end of the Ca-I'Cl, and ,by'backward pitch. 1 re for to the opposite pitch.

It is believed that the stock is acted upon as indicated graphically by the broken and whole lines used in all the figures except Figure 1, but this cannot be positively de termined. V V V In the drawings, Fig. 1 is a diagrammatic side elevation of the feed end of a card in some cases.

In the drawings, H represents the main oylinderof a oard'which runs forwarr and has. card clothing teeth which pitch forward. F is a tumbler which runs backward and is covered with card clothing haying teeth which pitch backward. have round wire teeth. 7 V

C represents a worker which preferably takes. the place of the first worker on the card or is located in front'thereof that is in positione that the stock will reach it before it reaches the first card clothin covered' worker.

This worker G is covered with flat wlre tooth card clothing, preferably ofthe saw tooth garnett, rigid type,

the teeth of which have considerable pitch and rake forward. I prefer that this should run backward 'but,' as shown in Fig.3, it

may run forward.

D is abreast cylinder in position tobe stripped by turnbl r F and to card with.

worker Cy lt'is'preierably covered with flat wire tooth clothing which, I prefer,

should be of the garnett wire tooth type. It

runs forward and its teeth-pitch forward.

-K and L are the feed-rolls of any usual construction, and E represents a lickerin which takes the stock therefrom-in a well known manner. This lickerin is preferably of the burroll type and preferably runs forward so as to carry the, stock upward, but it may be provided with any other kind ofteeth and may run downward, as shown in Figs. 6,7 and 8; j

B representsa stripper shown as ofthe flat garnett wire type with teeth which pitch 5 backward and-which run backward in position to strip worker C and to be cleared by breast cylinder D. In all the views, the main cylinder H is supposed to run with Both a surface speed of about 900 feet per minute, the tumbler F at from 400 to 500 feet'per 1ninute, are, the lickerin E, when running forward, about 200 feet per minute, the breast cylinder D from 200 to 300 feet per minute, say 220, the worker C at about 30 feet per minute, and stripper B 100 feet per minute." lt is believed that such relative speeds give best results.

. Referring to Fig. 2, the stock is delivered at 9 by feeding in rolls K and L and is carried upward to the point 10 by bur cylinder lickerin E. A partofthe stock is pulled well into the teeth of E and remains there, as shown by the full line, and passes over E, under F and on to H. VThis'stock is relatively small and line and is stripped from E by F, from which it is clearedby main cylinder H.

The locks, knots, pieces of cloth, etc, which stand up above the teeth on lickerin E, as indicated by the line of loiisg'daslies and dots, is'picked oil at the point 10 by breast cylinder D and carried along up to the point 13 where it is mixed with other stock'taken from stripper Vi hen the stock reaches the pointct card ing contact 16 with the worker C it is divided, the locks, knots, etc, which stick up being; pulled into the teetah'of? worker C, as shown by the line of dot, dash, dot, dash, while the Smaller pieces and the stock which is better mixed and carded remains on breast D, as shown by the line of long dashes, andis stripped therefrom the point 18 by tumbler F, from which it is stripped at the point 19 by main c din der H. V i I V The stock taken from tumbler F by main cylinder H is carried along to the point of carding contact 17 with worker C, where any knots, l cks, etc which stick up above the teeth of the main cylinder are pulled into the rigid or semi-rigid teeth or the worker, while the finer parts remain'in round wire teeth of the main 'cylinder'and at about continue onto befurther carded by the regular card clothing workers W? and Vt and to be actedon by the regular strippers S andSflas shown in Fig. 1. 7

. The stock picked up by. the teeth of worker C at the point 16 and at the point 1.7

is carried; upward. and back, and at the point 15 is'strippe'dtherefrom by stripper 13, from which, at its point of stripping contact'13 with breast cylinder D, it is stripped and mixed with the other stock shown roughly between the points 13 and16; The

stock which is carried'ojver byjworker C is shown'bya line of dashesranddots and by another line of shortdashes.

In Fig; 3, all'parts' are the sam e -eXceptv worker Q, whose, teeth-pitch the: same-for ward way but which ,tra'vels forward. The result of this movement isthatthestock,

shown by the short dashes, taken from the main cylinder H at 17 is carried downward and backward and is re-carded at the point 16. At this point 16 it is mixed and carded with other stock which comes from the point 13. The stock which is least mixed and stands on the points of the teeth at 16 will generally be pulled into the teeth of worker C and, as shown by the line of dash, dot, dash, dot, will be carried up and back and will be stripped at the point '15 by worker 13 and carried back again until cleared from the stripper at 13 by breast cylinder D.

In Fig. 4:, I show the same construction as Fig. 2 except that I add another worker A provided with flat wire teeth which rake forward, while this worker preferably travels backward. The operation is substantially the same as that shown in Fig. 2 except that I gain an additional carding point between worker A and breast cylinder D at 11, whereby the rough stock which sticks up on the points of the teeth D is pulled apart, and what remains on worker A is stripped therefrom at the point 12 by stripper B and returned to breast cylinder D at the point 13. This worker A may travel at about 30 surface feet per minute.

In Fig. 5, lickerin E is shown as covered with saw tooth garnett wire, and I show an additional worker G which travels forward and has teeth which pitch forward and a stripper R therefor having teeth which pitch backward and which runs backward.

In this view, worker C is supposed to travel about 30 feet per minute, stripper B about 30 feet per minute, worker G about 60 feet per minute, and stripper R- about 100 feet per minute.

The action of the stock on lickerin E, tumbler F, worker C and the main cylinder is the same as before, but stripper B serves as a transfer roll which carries the stock, shown in the line of short dashes and dash, dot, dash, dot, over from worker C to the point 14 where it is stripped by worker G and carried down to the point 11 where recarding takes place, some being carried back to the point 10, where all is stripped by stripper R, and carried around to the point 11 whence it is stripped by breast cylinder D.

In Fig. 6, the lickerin E is shown as separated from tumbler F and as traveling backward, with garnett teeth which pitch backward, the construction being otherwise the same as in Fig. 5. The stock taken from the feeding in rolls at 9 travels down instead of up, as shown by the double full lines. and is all removed at the point 50 by the breast cylinder. With some classes of stock, this downward movement permits foreign matters, like buttons etc., to drop to the floor.

The action of the workers C and G and strippers B and It is substantially the same, the stock being carded and re-carded until stripped from the breast cylinder D by tumbler F and delivered to the main cylinder at 19 whence it is carried along to the point 17 as in the other constructions. At the point 17, any unmixed or unseparated material which sticks up on the teeth of H is picked off by the rigid or semi-rigid teeth of worker C, as before described.

In Fig. 7, the lickerin E is shown as a bur roll running backward, with teeth which pitch backward and out of contact with tumbler F.

In addition to worker C and stripper B, I show another independent worker M which runs forward, with teeth which pitch forward, and a stripper N therefor which runs backward, with teeth which pitch backward, both of garnett wire.

The stock received by bur roll E at 9' travels down, as shown by the double full lines, and is picked off at 50 by the breast cylinder D and is first carded at the point 43 by worker M from which, at 4:4, it is stripped by stripper N and returned at 45 to the breast cylinder. From this point it travels-along to the points 13 and 16 where it is treated in substantially the same way as shown and described in Fig. 2. Worker M may travel at about 30 feet.

In Fig. 8, lickerin E is shown as running backward and is covered with card clothing and is out of contact with tumbler F. lVorker C and stripper B are the same as shown in the other views, but I show an additional worker P which travels forward and has teeth which pitch forward and is in carding contact with breast cylinder D and in stripping contact with stripper B.

In this construction, stripper B travels 100 surface feet per minute, and worker P, 30 surface feet per minute so that it will be stripped by B.

Where the lickerin runs down or backward, as shown in Figs. 6, 7 and 8, either the breast cylinder D should run faster or the lickerin slower in order to be kept clear. For the speeds indicated heretofore, a surface speed of the lickerin of about 100 feet per minute would be suitable.

In Fig. 9, I show a roll 0, which might be called a lumper, covered preferably with flat wire, shown as garnett wire, with teeth which pitch backward and runnin backward at a slow surface speed, of pei l iaps 80 feet per minute, in carding contact with tumbler F and in stripping contact with lickerin E.

The effect of this roll is to pick off any rough stock which stands up on the teeth of tumbler F and to carry it. as shown by the line of three dots and a dash, from point 53 on the tumbler to the point 5% on the lickerin, by which it is carried back to the pointof contact 9 with thefeed rolls, from which it goes through the breast again. Roll 0 thus serves as a guard to keep rough stock from the main cylinder, but also prevents high speed, is thrown outward by centrifu gal force and, as thereis no stripper between Worker C and H, it is caught and pulled into the teeth of C by which it is carried back to the breast cylinder D and re-worked.

Another reason why I prefer to run my lickerin E forward is that the stock is pulled V apart atthe point 9-and again at the point 10 so that, as it is carried up by breast cylinder D, anybuttons, pieces of metal, and other substances WhlGll, would in ure the teeth are thrown off and gradually work along between 9 and 10 until they fall off, 7 the end of roll E onto the floor. "curs'before they are crowded between the teeth of ,anytwo rolls and at the time when the stockis-enoughseparated so thatithey' This 'oc will fall out of it.

In Fig. 10, I show the roll 0 as it can be used where the lickerin and tumbler are not, 1nengagement, as shown in Figs. 6 and 8.

In. this case, the flat wire covered lumper roll O'is inserted between cylinder D, lickerin E and tumbler F, with its -teethpitching backward and slow speed. V V v The result of this arrangement is that, at its nearest point 57 to lickerin-E, it pulls apart the stock, taking some which sticks up on the teeth'and, as shown by the line of two dots .and'tw o, dashes, carries it around tothe nearest point 56 on cylinder D, and at" 55 it catches any coarse stock which stands up on the teethof theftumbler and carries this also, as shown by the line of three dots and dashes, back until it is strip'ped'at the point 55by-breast cylinder D' all such stock bein carried back to the:

point .50.: It will be observed that something in the nature of carding occurs at the points 57 and 55. y I

It wil also be understoodthat, with some classes of stock, it may be advisable to move I this lumber: roll far enough. away either from the liclrerin or the tumbler so, that no actiontakesiplace, but in every case it should run at a'speed Sll'fllClfilltlYSlOW, as ffrom 3O to 100 surface feet per minute, so that it will be stripped eitherby the lickerin or the breast cylinder. t is prefer bly covered with flat wire, as this keeps clean better than round wire card clothing.

runningforward ata V :ljsessia My breast properly includes abreast cylinder, a flat wire worker in carding contactwith'itand with the main cylinder, and a stripper between the worker and the breast cylinder. In my preferred construction, I preferto use a forward running lickerin -with a tumbler in strippingcontact there with.

Except for the added difiicu'lty'of locating and thediificulty of watching its operation,

@keeping it clear, etc, I prefer also to use the bumper roll 0 as shown in Figs. 9 and 10.

In attaching mypreferred form of breast to the ordinary card, my fiat wire tooth worker takes the place of the first card clothing covered worker and no change is required in the location of the .lickerin and tumbler; V V n 5 v V H The construction shown in Figs. 1, 2 and 3, with a single worker C, is verysatisfam tory, but in many cases, I can conveniently and economically use an eXtrawo-rker, such as A, Fig. 4, orP, Fig; '8, stripped by the same stripper, thus lying. an extra card ngpoint. Except for ie expense-and the fact that the work cannotas readily be seen, I

find the combination of two workers, as shown in' Figs. 4, and 8, with a lumper roll, as shown in Fig.510, is yerysatisfactory. Iclaimtlf 1.
